Spain runs a separate income tax treaty with each country: with the United States since 1990 (protocol in force November 27, 2019) and with Canada since 1976 (protocol in force December 12, 2015). Both give Spain first claim on Spanish rental income and sale gains and leave the home country to relieve the double tax through a foreign tax credit.[IRS, Spain tax treaty documents (1990 convention and 2013 protocol), 2026-07] They split at the edges: the Canadian treaty covers taxes on capital, the US treaty income taxes only. That difference frames the most misunderstood cost of owning Spanish property, the wealth tax.
Read both documents as ordering rules, not shields. Three provisions decide most property-owner outcomes: the Article 4 residence tie-breaker, the Articles 6 and 13 rule that the country where the property sits taxes first, and the covered-taxes article, which matters most for what it leaves out. The rate caps on dividends and interest that fill most treaty summaries rarely touch a property file.
The two treaties at a glance
| US and Spain | Canada and Spain | |
|---|---|---|
| Signed | February 22, 1990, Madrid | November 23, 1976, Ottawa |
| Modernizing protocol | Signed January 14, 2013; in force November 27, 2019 | Signed November 18, 2014; in force December 12, 2015 |
| Covered taxes | US federal income taxes; Spain’s individual income tax (IRPF) and corporation tax | Taxes on income and on capital |
| Spanish rental income | Spain taxes first (Article 6) | Spain taxes first (Article 6) |
| Gains on Spanish real property | Spain taxes first (Article 13), including shares of property-rich companies | Spain taxes first (Article 13) |
| Private pensions | Taxable only in the residence state (Article 20) | Source state may tax periodic pensions, capped at 15% of the gross payment (Article 18) |
| Wealth tax | Not a covered tax | Capital article: Spain may tax capital represented by Spanish immovable property (Article 22) |
| Citizenship reach | Saving clause: the US taxes its citizens as if the treaty had not come into effect | No equivalent citizenship claim |
The Canadian protocol also cut dividend withholding to 5% for substantial corporate holdings and 15% otherwise, set interest at 10% with arm’s-length exemptions, and added assistance-in-collection machinery: CRA and the Agencia Tributaria can now collect each other’s assessed tax.[Supplementary Convention amending the 1976 Canada-Spain tax convention, in force December 12, 2015, 2026-07] The US protocol moved interest, royalties, and most direct-dividend and capital-gain categories to residence-only taxation and added mandatory binding arbitration: useful for corporate structures, largely beside the point for an individual with an apartment in Valencia.
The tie-breaker: which country you belong to when both claim you
Spain’s domestic rule makes anyone present more than 183 days in a calendar year a Spanish tax resident on worldwide income, and captures anyone whose centre of economic interests sits there.[Ley 35/2006, de 28 de noviembre, del IRPF, artículo 9 — residencia habitual en territorio español, 2026-07] The US claims its citizens and green-card holders wherever they live; Canada claims anyone who keeps sufficient residential ties.[CRA, Income Tax Folio S5-F1-C1, Determining an Individual's Residence Status, 2026-07] Anyone splitting a year between Toronto or Chicago and the Costa del Sol should expect both countries to claim them.
Both treaties break the tie with the same cascade: permanent home, then centre of vital interests, then habitual abode, then nationality, then mutual agreement between the competent authorities; the step-by-step mechanics are in how tax treaties work. The order is strict. A retiree who sells the Canadian house and keeps only the Alicante apartment has answered the question at step one, whatever their intentions.
For Americans, the saving clause in Article 1(3) lets the United States tax its citizens as if the treaty had not come into effect. Winning the tie-breaker for Spain re-orders who credits whom; it does not switch off the US filing or US tax.[US-Spain Income Tax Convention (1990), Articles 1, 2 and 4, 2026-07] For Canadians, losing Canadian residence under the tie-breaker is an emigration event with a price: the deemed-disposition rules covered in departure tax on foreign property apply just as on a physical move. A tie-breaker claim is a residency decision with a bill attached, not a form-filling exercise.
Spanish property income: Article 6 gives Spain the first bite
Both treaties say the same thing about rental income: income from immovable property may be taxed in the state where the property is situated.[Convention between Canada and Spain (1976), Articles 6 and 13, 2026-07] Spain taxes your Malaga rental under its own non-resident rules at its own rates; no treaty election moves that income home. The treaty’s contribution comes second: the home country taxes the same income again and credits the Spanish tax against its own.
How the credit works, and fails, is in rental income taxed in two countries; the Form 1116 computation in the US foreign tax credit; the T776 reporting and section 126 credit in CRA rules for foreign rental income. Spain’s non-resident rates, the empty-apartment imputed-income charge, and the EU versus non-EU deduction gap sit in the Spain pages for American buyers and Canadian buyers.
No configuration exists in which the home country taxes the Spanish rental and Spain stands down. Reporting the income only at home does not eliminate Spanish tax; it defers a Spanish assessment that the 2015 protocol’s collection-assistance article now lets Spain pursue through CRA.
Selling: Article 13 keeps the gain in Spain first
Gains from selling Spanish real property may be taxed in Spain under both treaties, and the US treaty extends the same rule to shares of a company whose assets are mainly Spanish real estate, closing the obvious workaround. The residence country then taxes the gain under its own rules and credits the Spanish tax.
The credit rarely lands cleanly, and the treaties are not the reason. Spain computes its gain in euros from the escritura price; the US in dollars from the original cost basis; Canada in Canadian dollars under its own cost-base rules. A decade of exchange-rate movement can produce a large home-country gain on a property that barely moved in euros, and the Spanish tax credited against it covers only the euro gain Spain saw. Principal-residence relief adds a second mismatch, since each country tests the home under its own regime and the tests rarely all pass at once.
The wealth tax: the cost neither treaty absorbs
Spain levies an annual net-wealth tax, the Impuesto sobre el Patrimonio, established by Law 19/1991. Non-residents pay it on Spanish-situs assets only, with a state-level allowance of €700,000 EUR per person; regional surcharges and reliefs vary widely.[Ley 19/1991, de 6 de junio, del Impuesto sobre el Patrimonio, 2026-07] Since December 2022 a state solidarity tax on net wealth above €3,000,000 EUR sits on top, built to backstop regions like Madrid and Andalucía that relieve their own wealth tax, and it has been extended indefinitely.[Ley 38/2022 — Impuesto Temporal de Solidaridad de las Grandes Fortunas, extended by RDL 8/2023, 2026-07]
The two treaties take different routes to the same result. The US-Spain covered-taxes article lists Spain’s individual income tax and corporation tax. A net-wealth levy is not on the list, so the treaty neither restrains Spain from imposing it nor obliges the United States to do anything about it. US domestic law doesn’t step in either: the foreign tax credit is available for foreign income taxes and taxes in lieu of income tax, and a tax on asset values does not qualify.[IRS Publication 514, Foreign Tax Credit for Individuals — taxes that qualify for the credit, 2026-07] An American who owns a €1,200,000 EUR villa in Marbella pays Spanish wealth tax with no US offset. It is a carrying cost, priced into the purchase like community fees.
The Canadian treaty looks better on paper and lands in the same place. The 1976 convention covers taxes on income and on capital, and its capital article states that capital represented by immovable property may be taxed in the state where the property is situated. That confirms Spain’s right rather than limiting it. Because Canada levies no net-wealth tax of its own, there is no Canadian capital tax to credit the Spanish payment against; the section 126 foreign tax credit is confined to income and profits taxes.[CRA, Income Tax Folio S5-F2-C1, Foreign Tax Credit, 2026-07] The Spanish wealth tax sticks, in full, every year either nationality owns the asset.
For most buyers under the €700,000 EUR per-person line this section is a non-event, and joint ownership doubles the allowance. Above it, the wealth tax belongs in the yield math before the offer goes in, not after the first Modelo 714 falls due.
Pensions and social security: the one place the treaties diverge sharply
The US treaty is clean: private pensions and annuities paid for past employment are taxable only where the recipient resides, while social security benefits may be taxed by the paying state.[US-Spain Income Tax Convention (1990), Article 20 — Pensions, Annuities, Alimony, and Child Support, 2026-07] An American retiree in Spain reports the IRA and 401(k) drawdowns to Spain as the residence state, while the saving clause keeps the US return alive and the credit machinery reconciles the two.
The Canadian treaty follows Canada’s standard pattern instead: periodic pension payments arising in Canada and paid to a Spanish resident may be taxed by Canada, capped at the lesser of 15% of the gross payment or a rate computed on the recipient’s total pension income.[Convention between Canada and Spain (1976), Article 18 — Pensions and Annuities, 2026-07] A Canadian retiree in Valencia keeps a Canadian withholding line on RRIF and pension payments for life, credited against the Spanish tax on the same income.
Contribution-side coverage is a separate instrument. The United States has run a totalization agreement with Spain since 1988, preventing double social-security contributions and letting split careers combine credits; Canada has a parallel social security convention.[US Social Security Administration, Totalization Agreement with Spain, 2026-07] The benefit-eligibility side is covered in totalization agreements and social security.
The Beckham regime breaks the treaty assumptions
Spain’s inbound-expatriate regime under Article 93 of the personal income tax law, the Beckham regime, taxes qualifying new arrivals under non-resident rules for a limited run of years. The trap for treaty planning: a taxpayer inside the regime is generally unable to claim treaty benefits, because Spain issues a domestic-law residence certificate that most treaty partners do not accept as treaty residence.[Agencia Tributaria, Manual de tributación de no residentes — régimen especial de impatriados (art. 93 LIRPF): opting taxpayers are not considered residents for double tax convention purposes, 2026-07][BDO Global, Spain — Special Tax Regime for Inbound Expatriates, 2026-07]
Every allocation rule on this page assumes treaty residence. Under Beckham, the pension articles, the tie-breaker, and the credit ordering can all fall away, and for a US citizen the regime does nothing to reduce the US side; citizenship-based taxation continues regardless. The regime can still be the right call for high employment income, but that is an eligibility-and-arithmetic question for the Spain tax guide for American buyers and an advisor who has run the regime against a US return.
Frequently asked questions
Does the US-Spain treaty reduce Spanish tax on my rental?
No. Article 6 lets Spain tax Spanish rental income in full under its own non-resident rules. The treaty’s relief arrives on the US return, where the Spanish tax feeds the foreign tax credit.
Can I credit Spanish wealth tax on my US or Canadian return?
Generally no. The US treaty does not cover the wealth tax and US law confines the credit to income taxes. Canada’s treaty acknowledges Spain’s right to tax Spanish-situs capital, but Canada has no wealth tax to credit it against. Treat it as a carrying cost.
Both countries say I am tax resident. Which wins?
The Article 4 cascade in whichever treaty applies: permanent home, then centre of vital interests, then habitual abode, then nationality, then mutual agreement. On the US side a treaty residency position is disclosed on Form 8833; on the Canadian side, losing residence triggers the departure-tax rules. US citizens remain US taxpayers under the saving clause whatever the cascade decides.
Do the treaties change reporting obligations like Modelo 720 or FBAR?
No. Information reporting sits outside both treaties. Spanish residents file Modelo 720 on foreign assets, US persons keep FBAR and Form 8938, and Canadians keep T1135, all unaffected by any treaty position.
Where this fits in the library
This page owns the treaty layer: who taxes first, what gets credited, and what falls through. The taxes hub holds the credit walk-throughs; Spain-side rates and buying-year taxes live in the country pages for American buyers and Canadian buyers; the Canadian home-side filings are in CRA rules for foreign rental income and departure tax on foreign property.
